Elastic unit combined tire

Abstract

The invention provides an elastic unit combined tire, which consists of a rim, rubber air springs, metal shells and tread rubber, wherein a certain number of lug bosses are formed on the circumference of the rim; a rubber air spring is arranged on each lug boss; a metal shell is arranged on an upper end plate of each rubber air spring; the tread rubber covers the surface of each metal shell; tailends of two adjacent metal shells are connected through a hinge; an elastic unit consists of one or a group of rubber air springs, the metal shells and the tread rubber covering the surface of the metal shells; and the whole tire consists of a certain number of elastic units and the rim. The combined tire can save massive equipment investment and reduce technical difficulties in processing; and during use, the elastic unit can be rapidly replaced, the service life is long, the safety is high, and the bearing capacity is adjustable.

Description

technical field [0001] The invention belongs to the field of tires, in particular to a large combined tire. Background technique [0002] With the rapid development of the mining industry and water conservancy, road and bridge construction projects worldwide, the production and demand of engineering tires are constantly increasing, and there has been a serious shortage of supply in recent years. At present, the production process of tires is formed by the preparation of various rubber sheets, and then the molding and vulcanization of tire embryos. With the increase of load tonnage, the specifications of engineering tires are also becoming larger. At present, the outer diameter of giant engineering tires has reached 4 More than one meter, which requires matching large-scale tire building machines and tire vulcanizing machines to produce and process them, the required equipment investment and technical difficulty are very large, which also makes the cost of engineering tires v...

AI Technical Summary

Problems solved by technology

At present, the production process of tires is formed by the preparation of various rubber sheets, and then the molding and vulcanization of tire embryos. With the increase of load tonnage, the specifications of engineering tires are also becoming larger. At present, the outer diameter of giant engineering tires has reached 4 More than one meter, which requires matching large-scale tire building machines and tire vulcanizing machines to produce and process them, the required equipment investment and technical difficulty are very large, which also makes the cost of engineering tires very expensive; on the other hand, engineering tires Long-term uninterrupted operation in places with harsh road conditions such as mines and construction sites, and the heavy load makes the tread easy to wear and the carcass is not resistant to puncturing and cutting, which can easily lead to early scrapping of tires due to puncturing and cutting, thus Affect the driving safety performance and service life of tires
